VALVE.

Application filed May 5,1914. Seria1No.83,470.

To all whom it may concern Be it known that I, HOWARD FIELDER, a citizenof the United States, and a resident of Franklin, in the county ofWarren and State of Ohio, have invented a new 1 and useful Improvementin Valves, of which the following is a specification.

My invention is an improvement in valves, and has for its object toprovide a valve for interposition in awater supply system forcontrolling the operation of a pump operated by the water from a citymain or other source of supply for supply- ,ing soft water from acisternor other container to fixtures, wherein the valve is controlledby the pressureof the said soft water. i

In the drawings :-Figure 1 is a diagrammaticview of the system, Fig. 2is a vertical section of one arrangement of the controlling valve'forthe system, Fig. 3 is a diagrammatic top plan viewof the pump and itsconnections.

The present embodiment of the invention comprises a controlling devicefor water systems, wherein the said device is arranged 'to control theflow of the water through the system. The controlling device referred tohereafter as a valve is in fact a series of valves.

Referring to Fig. 1 of the drawing, it

will be seen that the pump supported by the 7 base 24, receives waterfrom the city main or other source of supply by means of a pipe 1, thesaid pipe leading from the main to the valve chamber, wherein valvemechanism is arranged for directing the Water through the various portsto operate the pistons in the cylinders to reciprocate the said pistons,and the pistons are connected directly to plungers in the pump cylindersat the right of the base, and to operate the said .plungers to causethepump to draw water from the cistern or other source of water and topass from the pump cylinders to a compression tank or other place ofstorage.

A pipe 2 leads from the pump, that is, from the cylinders which operatethe pump to the fixtures which are to be supplied with city water. Itwill be understood that after the water has operated the pistons in thecylinders, it then passes by way ofthe pipe 3 to the pipe 2, and to thefixtures. The

pipe 3 provides a by-pass for the discharge or used'wa ter from the pumpto the fixture with the lateral branch of, a T 4*, which connectsthepipes 2.and.3, and a valve 6 is interposed 1n the fixture line cent tothe T 41* and. on the opposite sides of the T from, the pipe 3.

Another pipe 5 leads from the pipe 1;,to

the head of the controlling valve, a T ,l being inserted in the pipe 1,and the pipe 5 ,is connected with the lateral branch of the T. A valvecasing 18 is interposed in'the. pipe 1 on the opposite side of the T 1pump, and a second T l is interposed in the ;p1pe 1 on the opposite sideof thevalve cas ng 18 from theT 1 A T 3 is arranged inthe pipe 3 betweenthe pump and-the T 4*, and an elbow 7 connects the T 3 with I a valvecasing, to be later described, arranged at the lower end of thecontrolling valve and forming a part thereof. v

from the Thecasing28just mentioned is connected a to the other portionsof the casing of; the

controlling valve in a manner to bepresently described, and a pipe 8leads from the end of said casing 28 remote fromthe pipe 3 to thesewerconnection 20. With this arrangement the. discharge water from theinterposed in the length of the pipe 9,. for 5.

controlling the how of the water through thep1pe. The pipe? is a by-passfrom the pipe 1 to the pipe 10, and'the valve 9 is provided for closingthe by-pas's when desired. The pipe 9 connects the lateral branch of theT 1 with the lateral branch of a T 10", interposed inthe length of thepipe 10. A valve casing l0 is interposed I i in the pipe 10; between thepump cylinders and the T 10 and between the storage tank and the pump. y

In practice the tank 22 should. have a 'ca. pacity of approximately 30gallons,y,and a hot water tank 23 which is connected to thecompressiontankv in a manner to be press ently described, would haveapproximately" the same capacity or preferably a somewhat largercapacity. A pipe 11 leads from the storage tank 22 and the hot watertank 23 to the soft water fixtures, that is, to the fixtures where it isdesired to supply cold soft water. The pipe 11 leads from the upper endof the tank 23, and a T 11 is interposed in the length of the pipe, forconnecting the said pipe with the compression tank 22. A pipe 12supplies the soft water fixtures with hot water, the said pipe leadingfrom the top of the hot water tank as shown.

The pump for the soft water is connected to a source of soft watersupply, as for instance, a cistern or other place of storage, by meansof a suction pipe 13, and a pipe 14 -connects the pipe 11 with the pipe13, the said pipe 14 forming a by-pass or drain pipe, for permitting thecompression tank and the pipes 11 and 12 to be drained into the cisternwhen desired. This pipe 14 connects the lateral branch of a T 11arranged in. the pipe 11, with a T 13 arranged in the pipe 13, and avalve casing 14 is interposed in the length of the pipe 14, forcontrolling the flow of water through the said pipe. When it is desiredto drain the water from the compression tank and the fixture pipes 11and 12 it is only necessary to open the valve 14 A pipe 15 leads fromthe cold water line 'fixture pipe 11 to the controlling valve, the pipe15 connecting the lateral branch of a T 11, interposed in the pipe 11,with the controlling valve intermediate the ends of the said valve, anda valve casing 17 is interposed in the length of the pipe 15. The pipe15 communicates with the valve casing, and supplies the water to thevalve which controls the operation of the valve. The pipe 15 is merelyapressure pipe through which the water pressure in the pipe 11 andconnections is communicated to the valve.

A drip pipe 19 leads from the pump to the sewer connection 20, and atrap of usual construction is arranged in the pipe 20 between the pipe 8and the sewer proper. I

The improved valve shown in Fig. 2, comprises a casing consisting of anupper portion 25, an intermediate portion 26, and a lower portion 27,and a valve casing 28 is connected with the lower end of the portion 27.The upper end of the upper portion 25 of the valve is externallythreaded for engagement by a cap 29, the cap having a guide 30, for thevalve stem. A packing 31 is arranged between the upper end of the upperportion of the valve and the cap, and a valve rod 32 has its upper endreceived within the guide.

A piston or plunger 33 is provided at the lower end of the rod 32, and apacking 34 is seated in a cup-shaped depression in the lower face of theplunger. The valve stem 35 has its upper end reduced and threaded asindicated at 36, to engage a threaded opening in the rod 32, and a nut37 is threaded on to the reduced portion 36 below the packing. The upperportion 25 of the valve is provided with lateral outlets 38 and 39, forconnection with the pipes 4 and 5, respectively, and the lower end ofthe stem 35 is externally threaded, and is engaged by a sleeve 40, thesaid sleeve fitting over the lower end.

The sleeve 40 is provided with disks 41 and 42, at its respective ends,and follower nuts 43 and 44, respectively, are threaded on to the stemadjacent to the disks 41 and 42. The follower nuts hold cup-shapedpackings 45 and 46 in place against the disks 41 and 42, and the plungeror piston constituted by the disk 41, the follower nut 43 and thepacking 45 is in the upper portion or hard water portion of the valvecasing, while the plunger or piston constituted by the disk 42, thefollower nut 44 and the packing 46 is in the intermediate portion of thecasing or the cylinder'of the valve.

A packing 48 is arranged between the upper end of the portion 26, and aradial flange 49 on the lower end of the upper portion, and screws 50are passed through the flange and engage the portion 26 to secure theupper portion of thevalve to the lower portion. A packing 51 is arrangedbetween the lower end of the intermediate portion 26 of the valve andthe upper end of the lower portion 27, and the said portions are heldtogether by screws 52.

A valvestem 53 is arranged at the lower end of the controlling valve,the upper end of the stem passing through a central opening in adiaphragm or head 54, which closes the lower end of the portion 26 ofthe valve casing. The lower end of the stem extends through a species ofpacking for sealing the lateral branch of the valve casing 28 around thestem. The upper end of the stem 53 is threaded, and a disk 56 isthreaded on to the stem in the bore of the portion 26.

A cup-shaped packing 58 is arranged adjacent to the disk, and a followernut 57 is threaded on to the disk above the packing, the disk, thepacking and the follower nut constituting a plunger or piston in thelower end of the portion 26 of the valve. It will be noticed that belowthe port 65, the bore of the portion 26 of the valve is of greater sizethan that above the port, and since the plungers 424446 and 56-5758 fitthe respective portions of the valve, the lastnamed plunger is ofgreater diameter than the first-named plunger. Hence the pressure on thelower plunger is greater than the pressure on the upper plunger.

The lower portion 27 of the valve above referred to, comprises thediaphragm 54, which closes the lower end of the portion 26 of the valve,and a diaphragm 55 which of the casing 28, and the pipe 8 with thecloses the upper end of the lateral branch of the valve casing 28, andthe said diaphragms are connected by oppositely arranged arms 27*, sothat access may be had to the packing to be presently described.

The packing comprises a nipple having an opening through which the stempasses, and having a water space at the upper end of the nipple. A capnut 55 is threaded on to the upper end of the nipple and closes thewater space, and a packing disk 55 is arranged between the nut and theend of the nipple. A frusto-conical leather washer or ring 55 isarranged within the water space, the lower small end of the washerfitting the stem, and it will be evident that the water pressure whichgains access to the water space will tend to seal the opening around thestem, since the said pressure will tend to force the lower small end ofthe washer more tightly into contact with the periphery of the stem.

A valve 59 is held to the lower end of the stem 53, by means of a screw60, and a packing 61 is held in a cup-shaped depression in the lower endof the valve by means of the screw. The plunger constituted by theelements 5657-58 in the portion 26 of the valve is thus rigidlyconnected with the valve constituted by the elements 596061 in the valvecasing 28, and the valve 59 is designed to coiiperate with the seat 62,which is arranged transversely of the T or valve casing 28.

The pipe 7 communicates with one end other end. The pipe 16 has twobranches, namely, a branch 63 which opens into the portion 26 of thevalve casing at the upper end thereof and a branch 64 which opens intosaid portion at the lower end thereof. The portion 26 is also providedwith a port 65 for connection with the pipe 15. Any desired form ofheater may be connected with the tank 23, as for instance, the heater 66shown in Fig. l, the said heater being connected in the usual manner,one of the connections being indicated at 67.

In practice the portion 25 of the casing will be made of a good qualityof red brass,

the stems 35 and 53 of bronzed rod, while the cup-shaped packing 4:544Land 58 will be of suitable material, as for instance a good quality ofleather. The packings 31, -18, 51 and the packing 68 which is arrangedbetween the valve casing 28 and the portion 27 of the valve, may be ofpaste board downward until the valve 33-34 is seated on the seat 69,which is arranged between the ports 38 and 39. When the'pressu-re at theport 65 increases 'and passesto or above 40 pounds, it will force thevalve stem upward, acting against the plunger 42-4 4.6, and the valve333t will be lifted from its seat 69. When the waterpressure at the port65 falls below 15 pounds, the valve stem 53 will be lifted by thepressure from the motor, lifting the valve 596061 from its seat 62, sothat the motor can discharge through the casing 28, by way of the pipes37 and 8 to the sewer. When the pressure at the port 65 exceeds 15pounds, the stem 53 will be forced downward, seating the packing 61 onthe seat 62.. The packing 55 permits the stem 53 to work freely.

It will be evident from the description that no springs are used,neither is a flexible diaphragm necessary. Furthermore no packings areused to interfere with the free smooth movement of the valve stems.adjustment is required for diiferent'pressures for the reason that thevalve is entirely automatic in its action. The valve permits the motorto pump on either high orlow pressure. When the soft water pressure ishigh and the main valve is open the water from the main may flow morerapidly to the fixtures. In addition a large compression tank is notnecessary. It will be understood that from 15 to 40 pounds pressure,soft water will be stored in the compression tank and in the hot waterboiler and at 10 pounds pressure the soft water will force the uppervalve open, permitting the water from the main to go by way of theby-pass to the fix tures. The valve will dispense with the necessity ofrunning water through the fixtures until the desired pressure of softwater is attained.

The branch 63 of the pipe 16 is a drip or air pipe as is also the branch64:, and the said pipes carry off any Water that may collect between thevalves at the ends of the sleeve 40 and between the valve at the upperend of the stem 53 and the packing 51. They also equalize the airpressure. It will be evident from the description that the action of thevalve is controlled entirely by the water pressure, and that there areno springs, diaphragms or the like, to get out of order. This is afeature of extreme importance, since the valve can be depended upon tooperate properly without attention and to properly regulate the relativeflow of the soft and city water. Neither is it necessary to provide forvarying pressure since the valve operates in precisely the same mannerwhatever the pressure. When the soft water pressure is high and the citywater valve is opened the city water will flow more rapidly to thefixtures, and the soft water at any time desired can be drawn down untilit reaches the lower pressure Nov which relieves the pump allowing it tofurther supply the soft water until the cistern or other supply might bepumped empty. The improved valve permits the motor to pump precisely thesame on low pressure as on high pressure, and no large compression tankis necessary.

The pump arranged on the base or support 24: is of usual construction,consisting of two operating cylinders 71 and two pump cylinders 72. Thepump plungers are connected directly to the pistons in the operatingcylinders by means of piston rods 70, and the pistons in the operatingcylinders are operated by the water through the pipe 1 from the citymain. The valves in connection with the cylinders supply wateralternately to the ends of the cylinders to reciprocate the pistons, andthe water after it has been used is discharged by the pipe 3, to thesewer or to the fixture line in accordance with conditions to be laterdescribed. lVhenever the pump plungers move in one direction, they drawwater through the suction pipe 13 into that end of the cylinders awayfrom which the plungers are moving, forcing water out of the other endof the cylinders through the discharge, pipe 10 to the compression tank.011 the return stroke, the water just drawn in is forced out and wateris drawn into the other end through the suction pipe 13. The specificconstruction of the pump both as concerns the operating end and thepumping end forms no part of the present invention and for this reasonis not more fully shown and described.

To place the system in condition for operation, the valves 61718 and 10are opened, and the valves 9 and 1e are closed. The system is now readyfor operation and the water from the city main flowing through the pipe1 to the motor cylinders 71 will operate the pistons in the pumpcylinders to reciprocate the plungers in the pump cylinders 72. As theplungers in the cylinders 72 reciprocate, soft water will be drawn fromthe source of supply and supplied to the compression tank 22 from whenceit may flow by way of the pipe 11 to the fixtures and to the hot watertank 23. At this time, since there is no pressure in the pipe 15 and atthe port 65, the pressure of the city water at the port 39 will forcethe valve stem 35 downward, the pressure acting against the head 4i14t5,and will close the valy e 3334 against its seat 69. The pipe 1 is nowout off from the pipe 2, so that the city or dynamic water can no longerflow from the pipe 1 to the pipe 2, by way of the valve, but must flowto the pipe 2 by way of the motor. The motor will be operated thedynamic water reciprocating the pistons in the cylinder, and causing thepump to pump water from the cistern to the the valve 59 -'6061.

compression tank by way of the suction pipe 13 and the discharge pipe10. The discharge from the pump may flow to the city water fixture lineby way of the pipe 3, but there will be no pressure in this line, untilthe valve 5961 is closed by the increase of pressure in the compressiontank or soft water line. As soon as the soft water pressure issufficient to close the valve 59-61, the discharge water from the pumpwill flow to the city fixture line. After the city water lines arefilled the water will pass into the sewer, by way of the pipes 7 and 8,the valve 5961 being open until the pressure reaches 15 pounds. When thepressure in the pipe 15 and at the port 65 of the controlling valveattains 40 pounds, the stem will be lifted, opening the valve 3334t, andpermitting the city water to flow from the pipe or by means of the pipes5 and i to the fixtures, thus stopping the operation of the pump.Whenever the pressure in the pipe 15 and at the port 65 of thecontrolling valve falls below 4L0 pounds, the valve stem 35' will movedownwardly closing the communication between the pipes e and 5, and themotor will again operate when city or dynamic water is being drawn. Thusas long as the pressure in the soft water line is between 15 and t0pounds, the pump will not operate unless city water is being drawn.\Vhen the pressure falls below 15 pounds, the pump will begin operationand will continue until the pressure again reaches 15 pounds. T he waterpasses to the operating end of the pump by way of the pipe 1, and isdischarged by way of the pipe 3 to the city water fixture line 2, or byway of the pipe 8 to the sewer, depending upon theposition of the valve596061. Should the valve 59 til--61 be closed at the commencement of theoperation of the pump, it will be gradually opened by the dischargewater in the pipes 3 and 7, and the pump will then discharge by way ofthe pipes 7 and 8 to the sewer, that is, to waste. This will continueuntil some pressure is attained in the pipe 15,sutlicient at least tomove the valve stem 53 downward, and to close Should this valve 59-6061be opened at the commencement of the operation no water may be drawnfrom the city water line until a soft water pressure is obtained ofthree or four pounds. idince'at this time the city water fixture line isempty the three or four pounds of pressure in the pipe 15 and at theport 65 will move the valve stem downwardly to close the valve 59-60 onits seat 62, thus closing the communication between the pipes 7 and 8,and the motor discharge water will pass by way of the pipes 2 and 3 tothe city fixture lines. So long as the pressure in the pipe 15 and atthe port 65 of the controlling valve is below 40 pounds, the valve33-34;

time from the fixtures the valve. elements will occupy the position ofFig. v2, that is, the valve 3334: will remain open, the withdrawal ofthe water having no effect upon the valve 3433. The above will obtainwhen the pressure in the pipe 15 is below 40 pounds.

In the above case, the pump will not operate if the pressure in the pipe15 is above 40 pounds. If however, the pressure in the pipe is below 40pounds with these conditions, the pump will operate and the dischargewater will pass into the pipe 2, in stead of discharging to the sewer.With the pressure at the port 65 of the controlling valve at 40 poundsand the valve 33-34 open, when city water is drawn from the fixture lineit will be supplied from the pipe 1 by way of the pipes 4 and 5 to pipe2. Should the soft water be withdrawn from the fixture line until thepressure at the port 65 is below 40 pounds, and no water is being drawnfrom the city fixture line 2, the valve 3334: will close, so that thecity water will pass through the motor end of the pump when being used.After the pressure in the soft water line attained 40 pounds and thepump is stopped it will not again operate until the pressure in the pipe15 and at the port 65 has fallen to 15 pounds unless city water is beingused. The only condition under which city water can be drawn from thefixture line with the pressure in the soft water line, that is, in thepipe 15, below 40 pounds without the valve 33-34 closing, is when bothcity and soft water. are being withdrawn from the fixturessimultaneously.

Should city and soft water be running from the fixtures at the same timewith the pressure in the pipe 15 below 40 pounds, and should there be acessation of the running from the soft water line without stopping therun of the city water,the valve 3334 will close, and the motor willbegin to operate, and the city water fixtures will be supplied withwater by way of the pipes '3 and 2. Should-the withdrawing of the softwater again commence, the valve 3334 will not open, and the city'waterwill not change its course above mentioned, nor will-*the motor ceaseits-operation until. the pressure :at

"the-'port'65 again'reaches'40 pounds. When the pressure in the pipe 15is below 15 pounds, the valve 5961 will .stand open, and'the dischargewater from the motor end of the pump will flow by way ofthe pipes 7 and8 to the sewer, and will continue to flow in this manneruntil'thepressurein the pipe '15 again reaches 15 pounds. When this.pressure is attained, the valve stem 53 is forced. downwardly seatingthe valve 5961 and the motor will stop until conditions change. Shouldthe pressure in the pipe 15 stand at 20 pounds, and should then softwater .be withdrawn by way of the ffixtures, the motor end of the pumpwill not begin to operate until the pressure in the v pipe 15 has beenreducedbelow 15 pounds. When this occurs, the motor will begin itsoperation. When the soft water pressure is below 40 pounds and above 15'pounds the pump will operate only while the city water is being drawn.

It will be evident that the device in its simplest form may beconsidered as a valve casing having an intermediate portion and endportions, the intermediate portion .being that portion between packing51 and the inlet port 39,- the said intermediate portion having aninletport 65, each of the end portions being provided with oppositelyarranged poi'ts and with a valve between the members of each pair ofports for controlling the communication between the ports, theintermediate portion having a plunger on each side connected to theadjacent valve foroperating the same, and theplunger adjacentto one pairof ports beinga double plunger operated upon by the pressure from theinlet'ports 39and 65.

The upper plunger controls the by-pass 45 from the source of supply, tothe fixture supply pipe, so that whenthis by-pass is-open and thepressure in the, pipe 1 exceeds the pressure in the pipe 2, the dynamicwater,thatis,.the water under pressurewill by-pass without affecting themotor. "The.

lowerplunger controls the by-pass from the exhaust of the motor to thesewer, thus con-.. trolling the flow of the dynamic water from the'motorto. the fixturelineor to'waste.

The system, as a whole, combines two independent sources of water, thewaterof one source being .dynamic and the water of the othersourcestatic, whereina .pump passes the static water from the source toa com pression tank which in turn passesiton to the fixtures, convertingthestatic water'in' the tank to dynamicform atthe fixtures. The motorwhich'operates the pump-is con- 'nected with the source of dynamicwaterand is operated by. the said water," and .dis-I. water to the fixtureline charges thezsaid for this water. The operation ofthe pump.dependsupon the -c ondition of the. by-pass 4. 5 ,.and the disposal ofthe water from the pump depends upon the condition of the by-pass 78.When the by-pass 4E5 is opened, the motor will not operate and the saidby-pass is controlled by the pressure in the soft water line, and alsoby the pressure in the fixture line for the city water.

The compression tank and the pipe 11 may be drained into the cistern byopening the valve 14 The pump may be shut ofl from both water lines byclosing the valves 10 and 18, and the controlling valve may be cut offby closing the valves 617 and 18.

It will be understood that the pressure values stated are based on acity water pressure of 65 pounds, and that if the city water pressure isgreater or less, the values stated will vary in proportion.
